Intra oral (IO) X-ray images are most-used in the dental clinics in Japan today. And it is very important to introduce the filmless PACS. But there was no standardization to display the IO images like analog films, so they developed their original unique format on their hospital.
 In the other hand, the JJ1017 standard is also used between HIS, RIS and PACS as a translation format. But this JJ1017 was not popular in dental solution and only one case was reported in 2010. In this report, we tried the IO image for adaptation to this JJ1017 based on Hokkaido University Hospital's information system and propose some expansion of the JJ1017 standard.
 At first, in JJ1017, only three figures can be used to indicate teeth region. But it is too little to show all patterns of teeth. Then it is proposed that some external extension for tooth region. Secondly, it is necessary to layout the images correctly on viewer that some specific displaying template and their inside positioning code are defined. And it is proposed that the templates are recorded on the 6th and 7th digit of JJ1017–16M and their inside positioning code were also recorded on the 19th and 20th digit of JJ1017–16S.

 Given the complexity and broad scope of living donor liver transplantation (LDLT) in adults, it has been hard to visualize the liver transplant process that includes complications. This study presents the complete medical knowledge on adult liver transplant recipients, including anticipated complications, and encompasses the entire treatment process, using the descriptive method of the Patient Condition Adaptive Path System (PCAPS) to visualize the treatment process in LDLT recipients, and proposes a method for visualizing complex medical procedures conducted concurrently.
 It turned out that the LDLT knowledge visualized from the data on 80 cases of LDLT covered the status of 97.5% of the patients. This knowledge included the treatment in 10 of 12 complications. These results suggest that the LDLT knowledge can be applied to medical treatment, and clinical data can be accumulated effectively.

 Telecare-applicable diseases and elements required for telecare systems by individual pathologies have not been clarified for medical care workers to introduce telecare. Firstly, we constructed a telecare system with commercial products including an IP TV phone using a personal computer, pedometer, automatic hemomanometer, weighing scale, self-monitoring blood glucose device, pulse oximeter, and communication network to send self-monitored data to a server. Three general internists who participated in a feasibility experiment involving this system investigated the applicability of telecare for 33 diseases and 17 symptoms encountered in routine clinical practice employing the Delphi method, in which the 3 internists repeated consensus conferences. They prepared a list of constituent elements of the system including biological sensors when the system was applicable. An automatic medical thermometer and electronic stethoscope, which were tested with regard to connection alone, were also included as sharable sensors. Using a TV phone and/or some biological sensors, telecare was applicable for chronic diseases, such as hypertension, diabetes, chronic pulmonary obstructive disease, bronchial asthma, and congestive heart failure, and the system was applicable using a TV phone alone for dementia, depression, and atopic dermatitis. The application was difficult for the first examination in many cases, but an interview using a TV phone was useful for the screening of some diseases.

 [Summary]
 Our hospital is an acute care hospital with a total of 373 beds, focusing on pediatric and perinatal medical care. In recent years, our hospital has assumed a more pivotal role as pediatric, obstetrics and gynaecology departments in nearby acute care hospitals have been closed.
 [Objective]
 As part of our hospital's medical health care plan, a forecast was made regarding the number of patients likely to visit our hospital, taking into account the effects of hospital relocations and demographic shifts.
 [Method]
 Using the grid square method, we designed a patient map according to the respective departments visited by patients, based on current addresses obtained from patients who have received treatment at our hospital.
 Separately from this, by applying the Huff model, we made forecasts regarding the impact that other large scale hospital relocations would have on our hospital's patient numbers.
 In addition, we also made forecasts regarding future patient trends based on population estimates in secondary medical care areas.
 [Result]
 By the use of the grid square method, the making of the document which it was easy to do of it being understood was possible intuitively about the trend of the outpatient.
 In addition, a near result was provided about the prediction by the Hff model practically.
 [Conclusion]
 By applying the Huff model, it is possible to make short term forecasts on changes in patient consultation trends, caused by such factors as hospital relocations in medical care regions.
 In the absence of such major occurrences, it is possible to offer useful materials to assist with regional health care planning initiatives, taking into consideration demographic trends.

 There exists various “boundaries” in medical records: paper-based medical records are managed by each department for years and inpatient records are usually put into a folder for each admission; on the other hand, for electronic medical records, each record is typically stored in the subsystem that created the record. The more boundaries, the more effort required to reach the target record. Therefore, managing all records in a logically single place and accessing them in a uniform manner— i.e., integrated document management— are desirable in terms of clinical practice.
 The goal of our research is to demonstrate validity of integrated document management feature of DACS (Document Archiving and Communication System). In order to achieve this goal, we conducted an analysis of the system log of the DACS running at Osaka University Hospital to figure out how many document views across the boundaries actually occurred.
 As a result, a total of 137,040 access threads, each of which indicates the sequence of a patient's documents viewed by a physician at one time, were identified. We also found that 42.2% of the threads involved document views across department boundaries, 27.7% across admission boundaries and 69.1% across subsystem boundaries. The result implies validity of integrated document management of DACS.
